This is a new simulation of a rotating disk being illuminated by a stroboscope. You can control the speed of the disk and the frequency of the stroboscope, and see how the white spot on the disk appears. You can check all the cases of stationary appearance and the slow-motion appearance.
This simulation models Newton’s tube experiment, showing how air resistance affects falling objects. By removing air from the tube and flipping it, users can observe how a feather and a pebble fall differently in air but identically in a vacuum—demonstrating that gravity accelerates all objects equally when air resistance is removed.
Educational technology is more about strategically leveraging technology to enhance, transform, and even redefine teaching and learning than just merging education with technology. You have to be a strong educator equipped with learning theories, educational methodologies, and statistical analysis in the first place to be a successful educational technologist.
With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.
This interactive wave interference simulation demonstrates the fundamental principles of wave superposition using two sources. Users can adjust key parameters including wavelength, amplitude, phase difference, and source separation to observe how waves interact and produce complex interference patterns. The simulation features a real-time probe tool that displays individual wave amplitudes and their resultant superposition, showing constructive and destructive interference at different points in the field. The visual representation includes radiating wave fronts from both sources, with characteristic alternating bands of high and low amplitude clearly visible throughout the interference pattern.
These lines portray a tale of creation and vanishing. It describes the creation of a photon, its subsequent disappearance when an electron absorbs it on the cathode plate’s surface, the subsequent departure of the electron from the cathode, and lastly the eventual disappearance of the electron when it reaches the other plate and captured.
Using this simulation, you can experience the phenomenon of charging a metallic ball by induction in the first stage and charging the ball by contact in the second stage after the charged rod touches the ball. The displayed charges are for an illustrational purpose, and they are not seen in reality. You can disable the display of charges on the rod and on the ball.
In this simulation, you can try two situations, one in which the rod is positively charged and another in which the rod is negatively charged, and you will see that the two situations result in the same observation.
